PROCESS AND APPARATUS FOR EXTRAGTING NICOTINE AND OTHER OILS FROMTOBACCO SMOKE.

Application tiled July 5,

This invention relates to a process *for extracting nicotine and otheroils from tobacco smoke 'and to means for accomplisl1- ing` this resu'ltorcarrying outthe process.

One of lthe objects of the invention is Ato provide a processofthe-characterdescribed thatanay lbe lused with cigarettes, cigars orpipes and by 'means of vwhich any desired percentagefd-lthenicotine orother oils may be extracted from the ytobacco smoke.

VAnother object ofthe invention is to Ypro-A vide` means "forkextracting and collecting nicotine and other oils so constructed and arol'the nicotine extracting device shown `in Fig. '3 isfa sectional`elevation ofanother form of extracting and `collecting means adapted'lor 'use with a cigarette or cigar holder.

lThe'inventionmay be'briefly described as consisting of ya process forextracting nicotine Aand other oils *from tobacco smoke which consistsof causing the smoke-ltomove ata-high velocity 'and tofimp'inge againsta condensing-surface. `Various 'forms of mechanical .devicesl for-carrying out this process havebeen .illustrated butin each of theseforms thesmoke is caused to pass'through consticted openings :in am'eniber disposed in the path of movement `oi the smoke and a'condensing `surface .is disposed adjacent thev member "first mentionedand is spaced from 4the openings and ,positioned 'in the path of' thesmoke after the smoke has passed 'through the openings. In order topreventthenicotine jirom lreaching the end ofthe m'outli,piecelnieanshas alsobeen provided for collecting the nicotine.

Referring to the drawings the device is shown 'in Figs. "l and 2 initssimplest form and consists of a concaved-or dished mem ber 2havingVaifcylindrical orslightly tapered Wall'l 21 and a curved end '22.Y.This member as fshovvn Ain gFig. `1 is placed in a cigarette lholder.23` being heldv therein by frictionjand-the member v20 is provided withaplurality of constricted openings 24 which as "shown in lfFig. l areVspaced riromthe inner Wall `dtthe'cigarette holder 23.,` When theAsmoke is drawn Ythrough thecigarette holder bythe "smoker it passesthrough the openings "24 and because 'o'ifth'e constricted nature otheseopenings the sinokeisrcaused to move at a high lvelocity and Aimpingesagainstthe inner Wall ofthe cigarette holder 23 'whereupon nicotine androther oils `are condensed on 'the surface of theholder 23. The "size oftheopenings` 24 maybe determinedby.,experimentfand is properlyAproportioned Withre'spectto the distance from the openings to theinnerWall of theciga- I rette holder. By changing the size ofthe openings and.the .distance from the inner Wall o1c thehlder 23theamount of the oilsdeposited on fthe cigarette holder may be varied. p i

v'In F'gs. 3, .4f and 5 another `form of mechanical meansfor carryingoutlthe process is illustrated. In 'this form of the device thecigarette holder 'is `divided into a cigarette vengaging tubular member130 and a' mouth piece 3l.' These members are connected by an elongatedtubular member 32 having a slightly flaring end 33 adapted to engagelthe tapered end 34 of the member 30. The elongated member 32'has oneend 35 closed except for a plurality of constricted openings 36. Thecondensing surfacev 37 is positioned Within the elongatedy member 32 andis slightly spaced from the openings 36. This member 37 is carried atone end of a spiral spring 38 and is spaced from the closed end 35 0fthe elongated member 32` by one end 39 of the spring 38 Vwhich passesthrough the member, 37 and engages the closed end 35. The spiral spring38 extends entirely through the elongated member 32 as clearly shown inFig. 3. The spring 3,8 in addition to spacing the condensing member 37from the openings 36 also serves to collect the condensed oils and toprevent their reaching the mouth piece 31. The elongated tubular member32 also acts as an ejector since the member may be moved along themember 32 when the cigarette has been smoked thereby engaging theendWith the cigarette and forcing the cigarette from the tapered end 34 ofthe member 30.

In Figs. 6, 7, 8 and 9 is illustrated another and the preferred form ofthe invention. In this form of the device a conical tubular member 40 isadapted tokiit Within the outer end of a cigarette holder 41 and theapex of this member is provided With a cover 42 having an opening 43therethrough. A second conical member 44 having a closed end 45 isadapted to lit Within the member 40 and the closed end has formedtherein a plurality of constricted .openings 46. As clearly shown VinFig. 6 theopenings 46 are spaced from the inner Wall 0f the member 40and as the lsmoke is drawn through the cigarette holder it passesthrough the openings 46 and the nicotine and other oils are constructiona cylindrical member 50 hav-M ing one end 51 closed except for anopening 52 therethrough is positioned in the stem 53 of the pipe 54. Atubular member 55 having a laterally extending flange 56 intermediateitsends is positionedvvithin the member 50 With the fiange 56 abuttingagainst a flange 57 formed on the member 50. The flange 57 in turn abutsagainst the end of the pipe stem 53. A cylindrical member 58 ispositioned Within the member 55 and has one end 59 ,closed except forconstricted openings 60. A liningmember 61 is mounted in the mouth piece62 and the mouth piece and lining member are mounted on the other end ofthe cylindrical member 55. As the smoke The cover 42 of the member 40"is drawn through the pipe it will pass through the opening 52 andthrough the constricted openings 60 and the nicotine and other oils Willbe deposited on the spaced inner Wall of the member 55.

From the foregoing specification it Will be seen that a simple andeffective process has been developed for removing the nicotine and otherobjectionable oils from tobacco smoke. It will be noted thatk themembers may be easily and quickly taken apart and cleaned therebyrendering the device capable of repeated use. l

Although certain specific forms of the device for carrying out thisprocess have been illustrated and described, it Will be understood thatI do not Wish to limit myself to any particular mechanical means andthat the invention is capable of further modification. It will beevident therefore that other changes in the construction and arrangementof the various parts may be made Without departing fromthe spirit orscope of the invention as expressed in the following claims.

vWhat I claim is 1..A process for extracting nicotine and other oilsfrom tobacco smoke, which consists in accelerating the HOW of smoke froman initial velocity and causing'the smoke to impinge fully againstagcondensing surface.

2. A process for extracting nicotine andv comprising a tapered tubularmember hav ing vits large end open and having an apertured cover atthesmaller end thereof, and a second tapered member adapted to fit inthe open end of the first member and having a curved end at thesmallerend thereof, said second member having constricted openin s thereindisposed directly in the path of t e smoke andin close proximity to theinner Wall of the iirst member.

4. A device for extracting and collecting nicotine from tobacco smokecomprising a tapered tubular member and a second tapered member adaptedto fit Within the first member and having its smaller end closed andprovided with constricted openings, the smaller end of the second memberbeing in close proximity to the inner Wall of the first member, theopenings being so proportioned and so spaced from said inner Wall thatthe smoke Will pass through the constricted openings at a high velocityand Will impinge on said inner Wall.

5. A device for extracting nicotine and other oils from tobacco smokecomprising a tubulaimember and a second member adapted to fit Withinsaid iirst member and having a closed end in close proximity to theinner wall of the first member, said closed end having constrictedopenings therein, the openings being so proportioned and so spaced fromsaid inner Wall that the smoke will pass through the constrictedopenings at a high velocity and will impinge on said inner Wall.

6. A device for extracting nicotine and other oils comprising a tubularmember, a tapered member disposed therein, and having constrictedopenings therein in close proximity to the inner Wall of the tubularmember, the openings being so proportioned and so spaced from said innerWall that the smoke Will pass through the constricted openings at a highvelocity and Will impinge on saidinner Wall.

7. A device for extracting and collecting nicotine from tobacco smokecomprising a tubular member and a second tapered member adapted to litWithin the first member and having its smaller end closed and providedWith constrcted openings, the smaller end of the second member being inclose proximity to the inner wall ot' the irst member, thegopeningsbeing so proportioned and so spaced from said inner Wall that the smokeWill pass through the constricted openings at a high velocity and Willimpinge on said inner Wall.

In Witness whereof, I have hereunto set my hand this 30th day of June,1922.
